One Hour Of Chemical Demonstrations, S. Solomon, M. Oliver-Hoyo, J. Tian, B. Brook
Journal of Mathematics and Science: Collaborative Explorations
This article describes a diverse set of chemistry demonstrations especially selected to encourage student interaction and to be easily transported. The demonstrations may be presented at a level that can be tailored to any audience– from very young children to high school students planning careers in science. An ideal environment is a small classroom with 20-30 students where everyone can take part in the discussion. Once the chemicals are prepared, the collection of demonstrations takes about ten minutes to set-up, and one hour (or less) to perform. Very little is needed at the visiting site, no more than a table …

Richard W. Pohl: Distinguished Botanist, Marjorie Conley Pohl
Richard W. Pohl: Distinguished Botanist, Marjorie Conley Pohl
Journal of the Iowa Academy of Science: JIAS
In her biographical portrait of Dr. Richard W. Pohl, Mrs. Pohl provides an engaging personal perspective of her late husband, his development as a botanist, his career, and his family life. We gain a sense of Dr. Pohl as a dedicated scientist as well as a humanist. Although Dr. Pohl possessed an abiding curiosity regarding all things natural, he is best known and remembered for his focus on grasses. As Mrs. Pohl documents, this interest in grasses began in the late 1930's and continued throughout his life-ultimately he was regarded as an authority on grass taxonomy both nationally and internationally. …
Walking Thoughts, Hunter R. Rawlings Iii
Walking Thoughts, Hunter R. Rawlings Iii
Journal of the Iowa Academy of Science: JIAS
I've borrowed my title from a poem by Marvin Bell, a member of our Writers' Workshop, because I cannot think of state parks without thinking of my love for their hiking trails and the expansion of spirit they have brought me. State parks are more than nature preserves, more than recreational areas, though these functions are very important. They are also cultural and even spiritual resources, centers of emotional and psychic renewal.
Distribution And Abundance Of Prairie Plant Species In The Loess Hills, Thomas R. Rosburg
Distribution And Abundance Of Prairie Plant Species In The Loess Hills, Thomas R. Rosburg
Journal of the Iowa Academy of Science: JIAS
The species composition of grassland and ecotonal communities throughout the Loess Hills was studies between 1990 and 1993. Information pertaining to the latitudinal distribution of species in the Loess Hills, the abundance of species among community types (i.e., habitats), species persistence under woody encroachment, species associations, and resource partitioning among species is provided for the majority of grassland species occurring in the Loess Hills. The most abundant species on extant prairie in the Loess Hills include Bouteloua curtipendula (side-oats grama), Schizachyrium scoparium (little bluestem), Andropogon gerardii (big bluestem), Cornus drummondii (rough-leaved dogwood), Aster ericoides (heath aster), Carex heliophila (sun-loving sedge), …

Iowa's State Parks: A Various Language, Rebecca Conard
Iowa's State Parks: A Various Language, Rebecca Conard
Journal of the Iowa Academy of Science: JIAS
Iowa's state park system is distinctive because academically based natural scientists were instrumental in drafting the 1917 State Park Law, in shaping the initial policies, and in establishing the first parks. The mandate of the 1917 law was broad, but its original intent was to preserve and conserve natural resources; providing recreational enjoyment was secondary. Between 1920 and mid-century the founding vision was recast time and again by compromises that sprang from economic necessity, competing interests, and changing societal values. The ideal of resource protection has remained a guiding principle, however, in large part because strong personalities provided continuity of …
Hot-Packaging Reduces Lipid Oxidation And Improves Sensory Characteristics Of Cooked Turkey Meat, Maiko Ishikawa, Dong U. Ahn
Hot-Packaging Reduces Lipid Oxidation And Improves Sensory Characteristics Of Cooked Turkey Meat, Maiko Ishikawa, Dong U. Ahn
Journal of the Iowa Academy of Science: JIAS
The effects of two vacuum packaging methods (hot and cold vacuum packaging) on the storage stability and sensory characteristics of cooked meat were compared. Ground turkey breast and leg meat patties were cooked, vacuum packaged appropriately, and stored up to 22 days. Lipid oxidation was measured by the thiobarbituric acid (TBA) test. In addition, Total aerobic count and sensory evaluation (flavor, juiciness, tenderness, overall acceptability) were conducted. There was no significant difference in aerobic plate count by packaging methods; however, panelist rating revealed that hot-packaged turkey leg meat had higher juiciness and overall acceptability scores than cold-packaged ones. Although TBARS …

Midwestern Geology And Cornell College: The First 125 Years, Gene E. Hinman, Paul L. Garvin
Journal of the Iowa Academy of Science: JIAS
The history of geology at Cornell College can be traced back almost to the college's beginnings. Though not the first to reach geology at Cornell, William Harmon Norton, more than any other person, shaped the Department of Geology and set it on its course of excellence. Born in 1856, the son of a Methodist minister, Norton developed an ardent interest in geology in his boyhood. A graduate of Cornell in Classics, Norton was hired by his alma mater in 1876 to reach Greek, bur his avocation was geology. He spent most of his spare time on weekends and during summers …
Book Review - The End Of Science: Facing The Limits Of Knowledge, David Lopatto
Book Review - The End Of Science: Facing The Limits Of Knowledge, David Lopatto
Journal of the Iowa Academy of Science: JIAS
The June, 1997 issue of Harper's Magazine included a list of recently published books that have titles beginning with "The End of". There are thirty-one titles on the list. Publishers have been rushing to cash in on the public's emotional reaction to the coming end of the century. It is difficult to take some of these works seriously. Perhaps the hardest thesis to swallow is that science, including physics, chemistry, biology, and neuroscience, not to mention the social sciences and the philosophy of science, is coming to an end just as our somewhat arbitrary calendar ticks over to a new …

Forest Research In Iowa's State Parks - The Values Of Natural Diversity, Donald R. Farrar
Forest Research In Iowa's State Parks - The Values Of Natural Diversity, Donald R. Farrar
Journal of the Iowa Academy of Science: JIAS
Approximately 3% of Iowa's forests are contained in state parks and preserves. In addition to aesthetics and recreation, these protected forests provide a vital service in the unique opportunities they provide for forest research. As intact ecosystems where natural ecological processes dominate, they provide standards by which we measure the effects of livestock pasturing, methods of timber harvest, and other manipulations of managed forests. A number of current studies and public programs emphasize the importance of natural diversity in forests. They rely on state parks and preserves to provide a measure of potential diversity for a given region of the …
